Description

The device and method adjusted for automatic filter
Technical field
Recommender system is faced in various application fields for recommended project (product, TV, song etc.), for slowing down The select permeability of the user of selection is carried out in huge amount option.There are two types of universal methods to construct recommender system.At the first In method, the project indicated by multiple features and user preferences is according further to these feature representations.This method is commonly known as based on The recommendation of content.Alternatively, history is listened in the purchase/checking/for analyzing (can be with subsidiary assessment information) large numbers of users, With the likelihood between identification project or the likelihood between user.Then, new item is recommended to user using these likelihoods Mesh.The second method is commonly known as collaborative filtering.The new projects suggested in collaborative filtering method are the items liked with user The similar new projects of mesh, are also possible to the new projects liked with user as given user class.It note that in addition to multiple users' It buys/checking/and listens to information, which does not need the specific information about project itself.
In general, recommender system is as the filter for being filtered to the possible interested project of user.In order to This filter is set to be suitble to the expectation and requirement of user, the known method for example based on the sum of content based on collaborative filtering.
It is well known that in both methods of the sum based on content based on collaborative filtering, it is difficult to provide new user good It is good to recommend.Before recommended device can learn its hobby and can provide good recommend, new user must firstly evaluate big quantifier Mesh, wherein assessment two aspect (like/do not like) or in terms of with more main points (e.g., including Five aspects for liking degree do not like very much such as, do not like, is neutral, liking, enjoying a lot) it carries out.
The problem of creation or modification filter parameter prevent them to indicate the hobby of specific users be machine from with Talk with to understand user preferences at family.Another problem is the lattice for needing to be capable of handling with machine about the information of user preferences Formula.However, general user cannot understand or revise the format.Can be easily easily absorbed on a cognitive level by the user therefore, it is necessary to one kind and The user interface for indicating the data of user preferences can effectively be acquired.This is the friendship by cannot directly provide the user of this information Mutually the basic technology of information can be handled by leading to the problem of machine.
Being learnt by the United States Patent (USP) 7,836,057 that on November 16th, 2010 authorizes requires user to grade project again.? In United States Patent (USP) 7,836,057, it is proposed that a kind of such as to purchase the method/system for helping user to select product in vehicle.User is bright Many selection criteria relevant to given product type are really provided, and for every kind of selection criteria, in product selection course User any degree can be weighted to given standard using sliding block setting.Therefore, system returns to the list of the product of sequence, should Sort the weight based on selection criteria.Then, if user is dissatisfied to the sequence of product, user can be again to product List grading.Then, system is pointed out to obtain how the list graded again can adjust the weight of selection criteria.
The method suggested in United States Patent (USP) 7,836,057 has many defects, so that not adapting to more complicated judgement Journey such as sees any TV or what program is rented in video on demand library.In order to learn the taste of new TV user, and set Fixed a small amount of selection criteria is compared, and recommender system is more complicated.If studied using Naive Bayes Classification method, for compared with Multiple characteristic values pair can indicate that the taste of user (refers to the 2007ACM meeting report about recommender system using degree is liked It concentrates, Pronk, V., W.Verhaegh, the Incorporating User Control into of A.Proidl and M.Tiemann Recommender Systems Based on Naive Bayesian Classification,RecSys 2007,pp.73– 80,Minne-apolis,MN,USA)。
Term used in the paper, especially with like degree and anti-factor claimed to be suitable for the disclosure.The two Term has following relationship.It is assumed that r be it is anti-claim factor, then correlation is liked degree λ and is provided by λ=r/ (1+r).On the contrary, for given Like degree λ, related anti-title factor r is provided by r=λ/(1- λ).0.5 degree of liking represents neutrality, because it is produced as 1 Neutral anti-title factor.The possible range for liking degree is between 0 and 1, and the possible anti-range for claiming factor is in 0 and infinity Between.
Characteristic value is to can be with some performer or particular genre for occurring in for example given film or specific broadcast Time or specific broadcast channel are related.Offer does not sound feasible to the user interface of each offer sliding block of these characteristic value centerings Border.In addition, if including very more characteristic values pair, then user cannot be made to keep scanning the weight of all different characteristic values pair, And manually setting these is also unpractical selection.In addition, how in order to realize that the given of given list is commented again Grade does the same difficulty of explanation come the clearly feedback for adjusting weight and user.
The additional defect of United States Patent (USP) 7,836,057 is how to adjust selection according only to the list feedback individually graded again The weight of standard.The hobby of user is captured to generate television recommendations, single bulleted list too limits, so that cannot learn Constitute the slight change of user's taste.Hobby that user is captured to generate television recommendations needs a series of to grade again Step suitably selects the continuous list for requiring user to grade again in those steps.
For learning the taste of TV viewer, another defect of United States Patent (USP) 7,836,057 is to require user to this All items present in list are graded again.Quantity for carrying out the possibility project of selection by it is very more to answer With with the television-viewing that can carry out selection from the TV performance of current broadcast, video on demand content, YouTube film etc. The case where person, is identical, it is desirable that the given list that user grades again be likely to containing user it is ignorant one or more Mesh.Even if providing the additional information about project, such as type, user is still difficult to grade to it.Therefore, it is proposed that user exists Again it grades and deletes its ignorant project (for example, replacing using sundry item) before the list from table first.
Another defect of United States Patent (USP) 7,836,057 is can not to explicitly point out user in this way and not like in list Which project.Possible its likes all items, does not like all items, or only likes a m project, wherein 0 < m < n.Cause This, the another aspect of the preferred embodiment of the present invention is that user can be in lists before first project or at last After a project between any continuous item pair tab-delimited symbol, to provide between the project liked and the project not liked Boundary.

Detailed description of the invention
It is discussed in greater detail according to below with reference to following attached drawing to what the present invention was done, above-mentioned and its other party of the invention Face, feature and advantage become apparent, in which:
Fig. 1 is the graphical representation of the device of the automatic adjustment for filter parameter;
Fig. 2 is the graphical representation of the device in Fig. 1 to project rearrangement;And
Fig. 3 is the graphical representation of the alternative of the automatic adjustment for filter parameter.
Specific embodiment
Device 10 shown in Fig. 1 for the automatic adjustment of filter parameter be connected to display 12 and such as mouse, The physical user interface 14 of track packet etc..The device includes or is connected to the memory 16 of the tabulation including project x, should Tabulation includes multiple projects in an orderly manner, and wherein the sequence of project is determined by its grade.Each project is by expression item At least one characteristic value of purpose characteristic value characterizes i.In general, project x is by multiple characteristic values to (i1、i2、i3...) special Signization.Degree λ is liked in addition, specified to each project x.The grade of project x liked degree and define the project.16 energy of memory Enough it is the integration section of device 10, also can is the database that device 10 is connected to.
Device 10 further includes user interface section 18, processing unit 20 and display interface unit 22.
User interface section 18 is configured, to receive signal from physical user interface 14 and corresponding signal is forwarded to processing Unit 20.
Processing unit 20 is connected to memory 16, and therefore, is able to access that one or more classification of the items list, such as It is upper described.Processing unit 20 also makes display interface unit 22 generate the graphical representation for leading to classification of the items list on the display 12 Signal.Processing unit 20 is configured, to work as filter adjusts unit, as described below.
Fig. 2 is the expression of the device 10 adjusted for automatic filter, and wherein user arranges again on the display 12 Sequence rearranges project.The grade for rearranging change project of project on the display 12.Because the grade of project with It likes degree correlation, so different grade most probables causes the difference of project to like degree.Degree is liked due to project Characteristic value pair depending on characterizing project likes degree, so the variation of the grade of project eventually leads to the happiness of characteristic value pair The revaluation of joyous degree, the further detailed description done as follows.
In fig. 3 it is shown that a kind of alternative arrangement, wherein memory 16 is not intended to the device of automatic filter adjusting 10 ' integration section, but a part of remote data base.Therefore it provides processing unit 20 is allowed to access in remote data base Memory 18 data-interface 24.
Now, the operation of device 10 is described.
Basic idea of the invention be provided for new user a kind of television recommender systems or similar recommender system, by A series of continuous item lists are provided in interactive session, it is specified that its hobby-and therefore reconciling items filter it is easy simultaneously And convenient method, wherein requiring that user executes following step for each continuous item list.
1. user deletes its project for being not enough to grade to it to the understanding of project, it can use another project replacement and delete Project;
It grades again 2. user likes reduced sequence with user to the bulleted list of acquisition;
3. in addition, user can be in lists before first project or after the last one project in any company Tab-delimited symbol between continuous project pair, to provide the boundary between the project liked and the project not liked.
Device utilize include again information in the sequence of grading list adjust appropriate characteristic value pair like degree, It is middle to combine the information from list of currently grading again with the information from list of previously grading again.Then, it utilizes The adjustment parameter of the filter of recommender system determines next appropriate project list, wherein typically, continuous list and user's The matching of taste is become better and better.
For the list of grading again, user is only by the n tables to the end of given position drag and drop in project from the beginning 10 tables In new demand position.In this way, user, which merely has to the project in correct n, provides opposite user preferences.In psychological study It is well known that user is easier compared with it once to a project evaluation must provide absolute user preferences to one group of project Opposite grading is provided to one group of given project.
The list of initial head n inconsistent from personal taste well select however with user of grading again is opened Begin, deletes and be performed many times with ranking process again.First graded again list according to this, recommended device provide it is next Attempt n, head that indicate the taste of user slightly goodly lists.Again second n a list of grading provides pass for recommended device In the additional information of user's taste, in this way in next iteration, the list of n, further good head is obtained.It can be repeatedly this Again it grades iteration, until user is full to next head n lists of acquisition or to a series of next head n lists Meaning.For lasting improvement recommended device, can choose continuous head n lists so that single project in these continuous lists most Often have primary.In addition, continuous list is not also not that should contain item closely similar mutually for example for its associated eigenvalue pair Mesh.
In this way, user repeats to obtain the feedback for how well learning its taste about recommended device.It is believed that with one time one Aly only to the single project evaluation, the taste without further how well to learn user to recommended device, which is done, to be fed back, and the process is more It is helpful.Because more helpful (because repeating to feed back) and being easier to grade again, and replace individually assessing project, so Always excitation user persistently provides feedback.Therefore, it is recommended that device can provide significant recommendation in earlier stage.
In third step, user can wish that obtaining the project recommended thinks with it to not interested enough the item of recommendation at it Separator is set between mesh.In this way, user can not only provide opposite grading to one group of given project, and can be in absolute project In provide its hobby.Response in ordered list between two continuous items i and i+1 tab-delimited symbol, processing unit 20 will Decision threshold t is set as (λ _ i+ λ _ (i+1))/2.If before separator is located in first item, processing unit 20 will Decision threshold t is set as (λ _ 1 1+)/2.If separator is located in final race, that is, after project n, then processing unit 20 Decision threshold t is set as λ _ n/2.Classifier can utilize the project that decision threshold difference is liked and the project not liked. For example, its positive prior probability can be set as such as 1-t by the Naive Bayes Classifier realized by processing unit.Therefore, Separator correctly to define prior probability present in Naive Bayes Classifier, make classifier also distinguish the project liked with The project not liked.
In order to adjust " user's overview " (that is, filter filtering items) according to n, the head graded again lists, it is proposed that The following examples.In this example it is assumed that recommender system uses Nae Bayesianmethod, in the Nae Bayesianmethod In, directly adjust characteristic value pair related with the project occurred in this n lists likes degree.
Adjust characteristic value pair likes degree
For simplicity, it is assumed that the sequence of n given project assigns each project in n project based on recommended device That gives likes degree.Assuming that the group all may characteristic value provided to by F={ 1,2 ..., N }.Now, project x can be by son CollectionIt characterizes.
For each characteristic value to i ∈ F, real number value ri∈ [0, ∞] provides the anti-title factor of this feature value pair, so that item The skew factor r (x) of mesh x is by ∏i∈F(x)riIt provides.The degree of liking of related more intuition is provided by λ (x) and by r (x)/(1+r (x)) it provides.
Now, it provides and utilizes x1、x2、……、xnThe grading list again of n project of expression, problem are whether we can One group of assemblage characteristic value of enough selections and characteristic value pair is to F (x1)∪F(x2)∪……∪F(xn) in characteristic value i is liked Degree, so that λ (x1)>λ(x2)>...>λ(xn) the sequence for liking degree and project rearrangement (or rearranging) arrange The sequence of the tier definition of table matches.It is incremented by due to liking degree and the anti-transitions monotonic claimed between factor, so we can be with In other words this is expressed as whether we can will be selected to be F (x1)∪F(x2)∪...∪F(xn) characteristic value pair anti-title Factor, so that r (x1)>r(x2)>...>r(xn)。
